Super Bright Blue LED Driver

I was about to start a project when I got stumped. I need advice on what driver circuit would be best to drive 10-20 super bright blue LEDs off of batteries.

Thanks for the help.

P.S. If you need me to specify anything (which you probably will) just ask :)

If they are not power LEDs use THIS great wizard. Yo will need information like LED forward voltage, LED current, and desired driving voltage.
